Abstract: The relativistic calculations of energies and widths are performed for the lowest states of hydrogen and hydrogen-like neon. The calculations are carried out using the finite-basis technique combined with the complex-scaling method. The obtained results are compared with the available nonrelativistic and relativistic data.

Keywords: Stark effect, complex scaling.
